` METAL SASHI.

Application led July 28, 1922. Ferial No. 578,@97.

' of steel or other metal and of neat and bars andl vertical bars or muntinsso termed.

and arranged as to present rabbets of a character that when the sash is closed no putty will show on either sash face.

The means by which the above'robjects and others as will appear are attained will be readily understood from the following description..

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the draw- A ings are merely illustrative of one example of the invention.

ln the Aillustrated example of my invention the sash' is provided with a sash frame 20 extending about the same. The vertical side members of said :trame 20 as showny in Figure 13 are generally of U-shape with one leg of the U extending beyond the other and adapted to lie at a side of the jamb 21 of a window frame within a sto 22 as fully set forth in an a plication led yby me August 23, 1922, erial No. '583,750. Said vertical side member of the sash frame 20 is adapted to be received between the outer member 24v and the inner member 25 of the sectional vertical bars entering into my invention. In the form shown in Figure 14 the vertical side member 2()ab of the sash frame has one side extended to lie at a side of a jamb 21 of a window frame within a stop 22*l on said member 20a instead of being received between the anges presented by t e outer and inner vertical members 24, 25 of the vertical sash bars and is formed to lie against the inner surface of the 'flange of the T-shapedA outer member 24 and to u be secured to a right angle flange 25a on the inner sections 25 of the adjacent vertical sash bar. Y o

The horizontal sash bars 23 are made from structural',A elements 23a of approximately Hshape in'cross section as shown in Figure 11, one flange of the structure elements extending farther from the web at one side than at the other and the opposite flange is reversely disposed, that member of the flange extending the shorter distance from the web being at the opposite side of the web from the short member of the first flange so that the longitudinal side edges of the respective flanges are out of alinement for the purpose of bringing the side flanges of the bar 23 into alinement as in Figure 12 by bending the web so that its opposite side edge portions are in different planes and connected by an intermediatel member at approximately right angles, the result being .a web of approximately Z- shape, the Web being hereinafter referre to as of general Z-shape.

Each horizontal bar 23 has a cut-out 28 in the outer flange` said cut-outs 28 accommodating the front of the vertical members 24 so that the front surface of the vertical bar and the front surface of thehorizontal bar 23 Will be in the same plane. In ad dition to the main cut-outs 28 in the horizontal bars 23 there yis a cut-out 26 in the web at the cut-out 28 and there is a hole 27 preferably rectangular inthe intermediate memberof the Z-shaped web. The outer members 24 of the vertical bars are T-shape in cross section as stated, the stem of the T presenting a terminal 24a of reduced thickness so as to be received between spaced vertical flanges 25b on the inner side of each inner bar section 25 of the vertical sash bars or muntins, said sections 25 thus being of double T-form in cross section. The sections 25 abut against the top and bottom edges of the horizontal bars 23 when the members 24, 25 are brought together and inter-engaged with the horizontal bars 23. The reduced edge terminal 241 of the vertical bar members 24 are slotted to produce rectangular studs 29 each adapted to enter a hole 26 in the horizontal bar 23, the end of each stud lying against the outer flange of the horizontal bar 23 and in practice welded or otherwise fastened to said horizontal bar.

In practice the members 24 are placed in position in association with the horizontal bars 23 while the glass panes 33 are being placed and the members 25 are put in position after the glazing operation. Without the members 25 the members 24, it will be observed, present a double rabbet for the reception of the glass. An important advantage of the Z-shaped web 35 is that a channel is formed at the top and bottom of the space 4for each window pane. The channel at the bottom has a width to accommodate the lower edge of the glass 33 temporarily so that the glass may be placed by dropping it into the bottom channel of the horizontal bar and after the glass has been brought into the plane of the sash frame the glass may be lifted into the channel of the top horizontal bar after which the elements 34 are placed in position to center the glass.

With the outer and inner members 24, 25 of the vertical sash bars assembled in association with a horizontal bar 23, said` front and back members will lie in the front and rear planes 'of the horizontal bar and will be positively secured to the horizontal bar through the medium of the studs 29. lVith the terminal edge 24 between the flanges 25b of the inner sections 25, pins 30 are passed through registering holes 31, 31L in the rcduced part 24 and in the flan es 25".

The vertical bars as descri ed when assembled present vertical side channels. The channels accommodate the side edges of the glass 33 and said side edges are embedded in putty as indicated at 32 in the channels presented by the vertical sash bars. The arrangement 'is such that the putty 32 does not present a front surface nor a rear surface and is not apparent. The top and bottom edges of the glass 33 are accommodated in the channels of the horizontal bars 23 as shown in Figure 5. Said channels of the horizontal bars 23 may have clips, one of which is shown at 34 in Figure 5, the clips being generally of V-shape to present a vertical member lying along one vertical surface of the channel and the other extending obliquely inward beneath the glass 33. Both legs of the V-shaped clip are directed laterally inward on approx imately horizontal lines. the one terminal, 35, lying beneath the glass 33 and the other terminal, 3G, presenting its end to a side surface of the glass so that the clip centers the glass in the channel of the horizontal bar 23, the putty 32 completing the securing of the glass. In Figure 17 the web 23h of cross bar element 23, the equivalent of element 23, is thickened at 231 instead of being bent bodily to Z-form. The element 23g is produced by extrusion.

As shown in Figure 10 the vertical side edges 24b of the outer members 24 of the vertical sash bars overlap the opposed side edges of the horizontal bars 23 at the cutouts 28 in the preferred construction and practical carrying out of the invention and the overlapping 'portions have opposed curved surfaces, all as will clearly appear from Figure 10. v

In Figure l5 the horizontal member 37 may be taken as representing either the top rail of an upper sash having a wood sash frame or may represent the meeting rail of the lower sash. Tol secure the top horizontal bar 23b to the element 37, one flange member 23 of the bar 23b is directed horizontally to receive nails or other fasteners .indicated at 23l and entering the element 37.

As shown in Figure 16 the bottom horizontal bar 23" is securedto the bottom bar 20" of the sash frame by screws 20c entering threaded sockets in tlie underside of the bar 23. Said bottom sash bar 23 has one of its flanges directed horizontall in the form of a foot 23f to lie on top o the sash frame bar 20".

I would state in'conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit m lsell? strictly to the exact details herein 1llustrated, since,` manifestly, the same' can be considerably varied without departure from the spirit of the invention as defined in the appended claims.
